Trying to do some cheap mods over the winter to keep pace with some of the local LT1's around my town. So far ive picked up some Underdrive Pullies, a TPIS AFPR, SLP runners and base and plenup Port matched to TPIS Bigmouth gaskets. Comps 1.6 RR and Valve springs. I also have a Hawks Ramair box fitted to my '97 Replica WS6 hood. no i don't have headers or a catback, to confused of whats good to buy. Any rate Im hoping with these mods ill pickup about 20-30 RWHP and a few more RPMS of usable power.. am i dreaming or does this seem like good base. I can run a consistent 14.29 with my Nitto 555R's so im hoping to see some consistent 13s with these mods. Do you all think my estimate will be pretty close.

 

1) Do you mean the ASCD 97 Replica or the Suncoast one?
2) If it's the ASCD....how is fitment? I'm really in the need for this knowledge.

 

i have heddman shorty headers and y-pipe on my 87 IROC,and they are workin fine. they fit awsome and are pretty cheap.

 

i say go for long tubes/and somebody out there makes and offroad y pipe to connect them to a cat back i think it starts with an 'm' then i say flowmaster american thunder...i love it

 

I have Eibach Sportlines, car sits pretty low, i don't know if i would have enough clearance for Long Tubes. I think the company for that Y-pipe is Mufflex, but i hear it has serious fitment issues. And usually has to get chopped up.

 

what year is your car and is it a 350 or a 305?

with a set of Hooker competition headers into a 3 inch Hooker cat-back to add to what you've got you should be able to see ATLEAST low 14s with a 350, possibly even 13s..obviously a little slower if you have a 305.

 

I have a 350 L98. stock. Ive already pushed to a low 14.29 bone stock power with only change from stock are the Nitto555R Drag Radials. I would hope with Full headers and catback id hit a 13.6 or so.
